"studied the sine bar and angle setup stuff on classiccredentialexam.com the week before. honestly didnt think an mcq site would help with a hands on test but it made the angularity and flatness questions on the written part way less confusing. passed first try."
"put off studying for this one way too long, like two days before kinda late. the practice questions on dressing the wheel and workholding saved me, went in knowing what the evaluator would actually be checking for instead of guessing."
"was pretty skeptical going in but the mistake review feature actually pointed out i kept messing up perpendicularity and parallelism questions, which i didnt even relize was a weak spot til it showed me the pattern. recieved my results and it matched up with what i expected."
